WARNING/ALARM 36, Mains failure:
This warning/alarm is only active if the supply voltage to the
adjustable frequency drive is lost and 14-10 Line Failure is
NOT set to OFF. Possible correction: check the fuses to the
adjustable frequency drive.
ALARM 37, Imb of sup volt:
There is a current imbalance between the power units
ALARM 38, Internal fault:
If this alarm occurs, it may be necessary to contact your
Danfoss supplier. Some typical alarm messages:
0 The serial port cannot be initialized. Serious hardware
failure
256 The power EEPROM data is defective or too old
512 The control board EEPROM data is defective or too old
513 Communication timeout Reading EEPROM data
514 Communication timeout Reading EEPROM data
515 The Application Orientated Control cannot recognize the
EEPROM data.
516 Cannot write to the EEPROM because a write command is
in progress.
517 The write command has timed out.
518 Failure in the EEPROM
519 Missing or invalid BarCode data in EEPROM 1024 – 1279
CAN message cannot be sent. (1027 indicate a possible
hardware failure)
1281 Digital Signal Processor flash timeout
1282 Power micro software version mismatch
1283 Power EEPROM data version mismatch
1284 Cannot read Digital Signal Processor software version
1299 Option SW in slot A is too old
1300 Option SW in slot B is too old
1311 Option SW in slot C0 is too old
1312 Option SW in slot C1 is too old
1315 Option SW in slot A is not supported (not allowed)
1316 Option SW in slot B is not supported (not allowed)
1317 Option SW in slot C0 is not supported (not allowed)
1318 Option SW in slot C1 is not supported (not allowed)
1536 An exception in the Application Orientated Control is
registered. Debug information written in LCP
1792 DSP watchdog is active. Debugging of power part data
Motor Orientated Control data not transferred correctly
2049 Power data restarted
2315 Missing SW version from power unit
2816 Stack overflow Control board module
2817 Scheduler slow tasks
2818 Fast tasks
2819 Parameter thread
2820 LCP stack overflow
2821 Serial port overflow
2822 USB port overflow
3072-
5122
Parameter value is outside its limits. Perform an initiali-
zation. Parameter number causing the alarm: Subtract the
code from 3072. Ex Error code 3238: 3238-3072 = 166 is
outside the limit
5123 Option in slot A: Hardware incompatible with control
board hardware
5124 Option in slot B: Hardware incompatible with control
board hardware
5125 Option in slot C0: Hardware incompatible with control
board hardware
5126 Option in slot C1: Hardware incompatible with control
board hardware
5376-

ALARM 39, Heatsink sensor:
No feedback from the heatsink temperature sensor.
The signal from the IGBT thermal sensor is not available on
the power card. The problem could be on the power card, on
the gate drive card, or the ribbon cable between the power
card and gate drive card.
WARNING 40, Overload of Digital Output Terminal 27:
Check the load connected to terminal 27 or remove short-
circuit connection. Check 5-00 Digital I/O Mode and
5-01 Terminal 27 Mode.
WARNING 41, Overload of Digital Output Terminal 29:
Check the load connected to terminal 29 or remove short-
circuit connection. Check 5-00 Digital I/O Mode and
5-02 Terminal 29 Mode.
WARNING 42, Overload of Digital Output On X30/6:
Check the load connected to X30/6 or remove short-circuit
connection. Check 5-32 Term X30/6 Digi Out (MCB 101).
WARNING 42, Overload of Digital Output On X30/7:
Check the load connected to X30/7 or remove short-circuit
connection. Check 5-33 Term X30/7 Digi Out (MCB 101).
ALARM 45, Ground fault 2:
There is a discharge from the output phases to ground,
either in the cable between the adjustable frequency drive
and the motor or in the motor itself. Turn off the adjustable
frequency drive and remove the ground fault. This alarm is
detected under the start-up test sequence.
ALARM 46, Power card supply:
The supply on the power card is out of range.
There are three power supplies generated by the switch
mode power supply (SMPS) on the power card: 24 V, 5 V,
+/-18 V. When powered with 24 VDC with the MCB 107
option, only the 24 V and 5 V supplies are monitored. When
powered with three-phase AC line voltage, all three supplied
are monitored.
